Abstract
The investigation into CO2 conversion technologies has gained momentum due to escalating concerns about climate change and the pressing need for sustainable energy sources. While Ni-based catalysts have shown promise in CO2 methanation, they often exhibit moderate activity. In this study, we sought to address this limitation by incorporating La into Ni nanoparticles supported on SiO2 using the ammonia evaporation method. The La-doped Ni/SiO2 catalyst demonstrated a significant improvement in CO2 conversion, achieving a competitive 71.1 % compared to the 40.2 % observed with the Ni/SiO2 catalyst at 275 °C. This improvement is evident in the high space–time yield of methane (STYCH4) at 227.3 m..
